To all 'whom t may cof/wem.:

Be itVr known that I, Isaniiav WASHINGTON I SROMON, a citizen of theUnited States, and a resident-ofNVilkinsburg, in the county of.Allegheny and State of Pennsylvania, have 1invented a new and ImprovedStove, of

act description.

i which thev following is a full,clear, and ex- 'Ihis invention relatesto stoves, ranges and the like and has for an obyect to provide aconstruction wherein a maximum am-ount of heat'is absorbed by thearticles being vide "a gas stove arranged kwith pockets and associatedparts whereby excess heat from one pocket may pass to another pocket andthereby permit a 'more efficient absorption of t-he heat units while thestove is in use. A still .further object, more specifically, is `toprovide'a stove with a plurality of burners and pockets burners withconnecting tubes whereby the heat from one pocket may be caused to passto another pocket before it escapes to the draught. y

In the accompanying drawingse Figure 1 is -a side view-of a'gas stove,disclosing an embodiment ofv the invention. Figure 2 is a topv plan viewof thestove shown in Figure 1.

Figure 3is a sectional view through Figure l, approximately on line 3 3,the same desired construction as far as the ovenl and general-shape isconcerned,- -I-Ieretofore, in gas stoves, a suitable burner was providedand above the burner openings'weieformed, said openings being usuallycovered by a grating of. some `kind fory supporting ka pan f or otherarticle. This `*former structure by reason of this ope-n formation,permitted a large quantity of the heat units to'es'cape laterally andalso escape around the Vpan or.l other article being heated so that thevefficiency thereof was low. In order to in'- crease the efficiency andto utilize as many` ofthe heat units as possible, the presentinsurrounding the' vention includes a number'of lpockets whichare'indicated in the drawing as 2,3, l and .Iilachof these pockets isformed with al tubular section' having straight walls and y a curvedlower end which is adapted toreceive ya burner 6, which .burner maylbeof any desired type. The lower rounded'end l7 of. each of the.pockets 2 is p rovided with a number of air holes 8 whereby ample airis Pl'OVded" for securing the 'desired com; bustion'qof gas v v v vIn.each pocket a number otsupporting;

arms 9 are. provided :designedto' support a disk 10 of some suitablerefractory material,

as for instance, fire clay. :This disk is prov `vided with a number ofperforations to permit alarge percentage 'of the flame to passtherethrough. s Thisarrangement of pocket and'disll 10 is such thatthe'disk l1() becomes incandescent and, consequently,v 1 will con'-sumev most, if not all,"otf any soot or carbon produced by the burner.@when said soot strikes the incandescentdisl.-4 4Arranged at a desiredpointl above the arms9 isla second setof arms lladapted to ysupport anarticle to be heated,` as for instance, asauce pan 12 oriothercontainer; Thearins 11 niay,unde` r some circumstances, vsupport 'a-Aliner 13,

which liner is used when 'a shallow panis supported in the pocket inorder that the' upper part4v of the pan may project abo-ve the pocket.Preferably when eitherv a deep container` similar to container 12 isused or a shallow container, means are provided for preventing thelpassage-of any of the flame yor heat units out of the 'topof'the'pocket;

`This means consists of an annular ring 13 of asbestos or other `desiredmaterial which is preferably L-shaped in cross section and at the' leftin Figure 11, f

which, when in use, is positioned as shown By this construction andarrangement, they heat is applied to the bottom .of .the contailler-andto the sides but practically.' none y l can escape out the topf of thepocket. i In order to provide a proper outlet' or draught for theproducts of combustion, tubular pas-' 'V sage-ways 14, 15, 16, 17 and 18are provided,

The passage-ways 17 andv V18 i. merge togather as shown in Figure Bandalso merge into the outlet passage-way 19 which is con nected Vwith thedraught or smokestack 20.

Dampers 2l, 22, 23, 24C and 25are arran ed in the various passage-waysand control ed by suitable control rods 26 extending to the front of thestove. In case the pockets 3 and 4 are used, dampers 23 and 24 would bevopened and the remaining dampers closed as shown in Figure 3. This wouldcause the products of combustion to pass from the pocket 3 to pocket 4and fromthence to the outlet -19 so that pocket 4 would receive some ofthe heat from pocket 3. It will be understood that the dampers 23 and 24will be opened only to the proper extent to secure a proper draught formaintaining a desired combustion.

Under some circumstances, the pocket 2 might be used and the burner 6thereof used while the pockets 3 and 4 might be used without the burnerstherein being lighted.

It will, of course, be understood that most of the heat would be appliedto the article arranged in pocket 2 but an appreciable amount of heatwould be also applied to the articles of the pockets 3 and 4 for slowlycooking the same-or for maintaining the same `warm so that one burnerwould function in a certain sense as three burners. In case a iiatarticle was to be heated, as Jfor instance, an ordinary skillet whichwas too big to enter the pocket and rest on the liner 13, it could beplaced directly on top of thepocketand receive heat therefromsubstantially in` theusual manner except that the excess heat wouldpassout through one of the passage-ways extending `from the pocket. Inorderto provide a proper pocket for the stove, covering plates 27 might`be provided and supported by cross bars or any suitable means. In thedrawings, four plates 27 have been providedbut it willbe evident that asinglefplate might be used or more than four. In regard to the oven otthe stove, pockets similar to poclret'2 might be used or a burner of theold type provided as preferred.

lVhat I claim is :,--v

l.y A gas sto-ve, comprising a body,A a plurality of pockets carried bythe body, tubular members connecting said pockets, a damper arranged ineach of the tubular members, a burner arrangedin the lower part Aof eachof the pockets, a plurality of brackets in each pocket for supporting anarticle to be heated, and a packing member adapted to surround thearticle to be heated, said packing niember being positioned adjacent thetop of the pocket whereby excess heat and products of cmbustion will becaused to pass through certain'oi" said tubular members to adjacentpockets. Y Y

v2. In a gas stove, .a pocket substantially tubular open at one end andvclosed at the fractorydisk arranged on the other of said? arms adaptedto be heated to incandescency for causing a more thorough combustion. p

3. ln a gas stove, a `tubular pocket ystructure, a gas burner arrangedinthe bottom ot said pocket structure, a plurality of supporting armsarranged in said pocket'struo ture above the burner, a liner 'cage'mounted t on said supporting arms whereby ya co'm-` paratively shallowlarticle may be supported in the pocket and permitted to project there-1above.

A

5.
